启动tomcat时出错

Question

我正在尝试在Linux机器上设置Apache Tomcat。我已经安装了tomcat 6和java 7.启动tomcat给出：

Java HotSpot(TM) 64-Bit Server VM warning: Failed to reserve shared memory (errno = 22).
Java HotSpot(TM) 64-Bit Server VM warning: Failed to reserve shared memory (errno = 1).
Java HotSpot(TM) 64-Bit Server VM warning: Failed to reserve shared memory (errno = 1).
Error: SNMP ACL file not found: /srv/tomcat/conf/snmp.acl

有关上述错误的任何线索？
